BACKGROUND
The statements in this section merely provide background
information related to the present disclosure and may not
constitute prior art.
Often, furniture apparatuses capable of more than one function are
used in environments (e.g., residential, commercial, etc.) where
space is limited. For example, futon beds or other like foldable
beds may be used in such environments as sitting furniture (e.g.,
couches, sofas, etc.) and lying and/or sleeping furniture (e.g.,
beds, etc.). In these environments, futon beds may make more
efficient use of the limited space and may relieve the need for
additional furniture. However, even futon beds may take up too much
space in certain environments.

panel 130A may be connected to the base 150 via a second hinge 131.
In some example embodiments, the second hinge 131 may be a piano
hinge. However, example embodiments are not limited thereto.
While it may appear in FIG. 1 that the outer front panel 130A is
attached to the first sub-side panels 110A, as will be discussed
later, the outer front panel 130A may be adjoined to the first
sub-side panels 110A when the chest 10 is in the closed position
but may not be directly fixed to the first sub-side panels
110A.
The outer front panel 130A include one or more handles 132 provided
to assist in transitioning the chest 100 from the closed position
to the open position. The handles 132 may be any type of handle,
knob, latch, hook or and/or any other like protrusion or void that
allows an operator to manually grip the top panel 110. Further, the
outer front panel 130A may include pivoting guards 160 therein. For
example, the outer front panel 130A may include a pair of the
pivoting guards 160 in upper corners thereof. As will be discussed
in more detail below, the pivoting guards 160 may be secured by
pivot points to, for example, the outer front panel 130A.
The lower front panel 130B may include side portions attached to
each of the second sub-side panels 110B, where the first sub-side
panels 110A are configured to abut the side portions of the lower
front panel 130B when the chest 100 is in the closed position such
that a sum of the height of the side portions of the lower front
panel 130B and the first sub-side panels 110A is equal to a height
of the second sub-side panels 110B.
The chest 100 in the closed position is configured store a foldable
mattress 500 (see FIGS. 25 and 26) in an enclosure formed by the
side panels 110, the top panel 120, the front panel 130, and the
back panel 140. The foldable mattress 500 may be in a folded
position when stored in the enclosure.
As discussed in more detail below, the chest 100 may transition
from the closed position via movement of the outer front panel
130A, the first sub-side panels 110A and the first sub-top panel
120A from the closed position in which the outer front panel 130A
is parallel to a surface of the base 150, to a downward position in
which the outer front panel 130A is perpendicular to the surface of
the base 150.
When the chest 100 is in the open position, the back panel 140 may
function as a headboard for the foldable mattress 500.
Further, as discussed in more detail below, in addition to the side
panels 110, the top panel 120, the front panel 130, and the back
panel 140, which may be visible when the chest 100 is in the closed
position, the chest 100 may further include a folding slat deck
200.
Further, as discussed in more detail below, in some example
embodiments, a rear folding leg assembly 300 may be connected to
the first sub-side panels 110A and selectively extend therefrom to
provide additional support to the sleeping platform.
FIG. 5 illustrates a strap used to convert the chest between a
closed or folded position and an open or unfolded position
according to example embodiments. FIGS. 6 to 9 illustrate a chest
in an open or unfolded position according to example
embodiments
Referring to FIGS. 5 to 9, when the chest is in the open or
unfolded position, the first sub-side panels 110A are detached from
the second sub-side panels 110B, the first sub-top panel 120A is
detached from the second sub-top panel 125B and the front surface
of the outer front panel 130A is folded downwards such that the
front surface is parallel to a surface of the ground and
perpendicular to a position of the front surface when the chest 100
is in the closed position.
Further, as shown in FIGS. 5 to 9, in addition to the top panel
110, the front panel 120, the side panels 140, and the back panel
150, which may be visible when the chest 100 is in the closed
position, the chest 100 may further include the folding slat deck
200 in an inside thereof. Further, a strap 400 may be attached to
the inner front panel 130B.
The folding slat deck 200 may be attached to, for example, the back
panel 140 (or rear supports associated therewith) via one or more
third hinges 210. However, example embodiments are not limited
thereto. For example, the folding slat deck 200 may be pivotally
connected to the side panels 140 via protrusions protruding from a
rear of a first one of the second sub-side panels 110B and the
folding slat deck 200 that are connected to respective openings in
a rear of a second one of the second sub-side panels 110B and the
folding slat deck 200. Further, in other example embodiments, the
folding slat deck 200 may simply be manually liftable and/or
foldable without including any connection between the folding slat
deck 200 and the chest 100. By having the folding slat deck 200
foldable between the folded position and the unfolded position, the
mattress 500 may sit substantially deeper in the enclosure until
needed, thus, substantially reducing the height of the chest
100.
In regards to the upper sleeping platform, the folding slat deck
200 may transition between a folded position (see FIG. 25) and an
unfolded position (see FIG. 30), where the folding slat deck 200
may rest against supports on the inside of at least the second
sub-side panels 110B in the unfolded position to form the upper
sleeping platform. The supports may extend towards an interior of
the enclosure an amount such that the supports do not interfere
with placement of the mattress 500 in the enclosure when the
mattress 500 is in the folded position.
The inner front panel 130B may be connected to the first sub-side
panels 110A and the first portion 120A-1 of the first sub-top panel
120A such that the inner front panel 130B is connected to the outer
front panel 130A via the first hinge 121. The inner front panel
130B may include a rail 133 connected between the two first
sub-side panels 110A and a plurality of slats 134. The plurality of
slats 134 may be secured between the first portion 120A-1 of the
first-sub-top panel 120A and the rail 133. However, example
embodiments are not limited thereto. For example, the inner front
panel 130B may include a solid surface rather than the plurality of
slats 134.
Further, the inner front panel 130B may include front legs 135 and
rear legs 136 attached thereto. The rear legs 136 may include
rollers 137 attached to a bottom surface thereof. In some example
embodiments, as illustrated in, for example, FIGS. 6 and 7, the
rear legs 136 may be secured a distance away from the first portion
120A-1 of the first sub-top panel 120A and angled towards the rear
of the inner front panel 130B to allow sufficient clearance between
the rear legs 136 and the top panel 120 when the inner front panel
130B is folded into the chest 100. However, as discussed in more
detail below with reference to FIGS. 36-43, example embodiments are
not limited thereto.
At least the folding slat deck 200, the inside surface of the outer
front panel 130A and the slats 134 on the inner front panel 130B
may together form a sleeping platform to support a weight of the
mattress 500 thereon when the outer front panel 130A is folded a
downwards direction (e.g., 90 degrees), the folding slat deck 200
is unfolded in a downwards direction (e.g., 90 degrees) and the
lower support is unfolded (e.g., 180 degrees) such that the front
legs 135 and the rear legs 136 contact a ground. In the open or
unfolded position the combined weight of the sleeping platform and
the mattress 500 may be supported by the front legs 135, the rear
legs 136 and the base 150 of the chest 100.
FIGS. 10 to 24 illustrate a method of unfolding a chest from an
closed or folded position to an open or unfolded position according
to example embodiments;
Referring to FIGS. 10 to 28, as illustrated in FIGS. 10 to 12, in a
first operation to unfold the chest 100, the first sub-side panels
110A, the first sub-top panel 120A, the outer front panel 130A
along with the inner front panel 130B attached thereto may be
folded downwards from a first position in which the outer front
panel 130A is substantially parallel with the front of the base
150, towards a second position in which the outer front panel 130A
is perpendicular to the front of the base 150. As the outer front
panel 130A moves from the first position to the second position,
the pivoting guards 160 attached to, for example, the outer front
panel 130A may pivot about a pivot point thereof. As illustrated in
FIGS. 10 to 12, the pivot point of the pivoting guards 160 may be
offset towards a side thereof closest to the second hinge 131 such
that a weight of the pivoting guards 160 urges the pivoting guards
160 to automatically pivot outwards from a first position to a
second position as the outer front panel 130A moves from the first
position to the second position and may secure the pivoting guards
160 in the second position against a force applied in a direction
substantially perpendicular to the outer front panel 130A. However,
example embodiments are not limited thereto. For example, in some
example embodiments, rather than having pivoting guards 160, the
chest 100 may include fixed guards that extend from, for example,
the outer front panel 130A to inhibit (or, alternatively, prevent)
the outer front panel 130A from directly contacting the ground by
maintaining a gap between the outer front panel 130A and the
ground.
Note also, as illustrated in FIGS. 10 to 12, that due to the
angling of the rear legs 136, a sufficient clearance may be secured
to allow the inner front panel 130B including the rear legs 136 to
extend from within the chest 100 without interacting with the top
panel 120.
As illustrated in FIGS. 13 and 14, in a second operation to unfold
the chest 100, the first sub-side panels 110A, the first sub-top
panel 120A, the outer front panel 130A along with the inner front
panel 130B attached thereto may be further unfolded so that the
pivoting guards 160 contact a ground. As discussed above, the pivot
point of the pivoting guards 160 may be offset such that the
pivoting guards 160 are secured in the second position against a
force applied in a direction substantially perpendicular to the
outer front panel 130A. Therefore, the pivot guards 160 may inhibit
(or, alternatively, prevent) the outer front panel 130A from
directly contacting the ground, thus, enhancing the durability of
the chest 100 without the costs and weight associated with a set of
rails stored within the chest 100 to support the outer front panel
130A.
As illustrated in FIGS. 15-20, in a third operation to unfold the
chest 100, a user may begin to unfold the inner front panel 130B
by, for example, pulling on the strap 400 until the rear legs 136
(e.g., the rollers 137 attached thereto) contact the ground. At
this juncture, the pivoting guards 160 may still contact the ground
and support a portion of the sleeping platform.
Referring to FIG. 20 in conjunction with FIGS. 15-19, after
performing the first to third operations to unfold the chest 100,
the sleeping platform will arrive at the position shown in FIG. 20,
which is a static state of rest for all components. For example,
the outer front panel 130A has been lowered to the floor with a
weight w1 thereof supported by the hingeable connection at one end
to the base 150 by the second hinge 131 and on the other end by the
pivoting guards 160 sitting on the floor. Accordingly after
performing the first to third operations, the outer front panel
130A is at rest and static under a force of gravity g. Likewise,
the inner front panel 130B is also at rest with the inner front
panel 130B being hingeably attached to the outer front panel 130A
by the first hinge 121 with the center of the weight w2 of the
inner front panel 130B supported between the roller 137 and the
first hinge 121.
In this rest state, the sleeping platform may form a lever with the
roller 137 considered a fulcrum of the lever with the weight w2 of
the inner front panel 130B acting on a left of the fulcrum, and
counter-balanced by a portion the weight w1 of the outer front
panel 130A acting through the second hinge 131 with the remaining
portion of the weight w1 of the outer front panel 130A supported
through the pivoting guards 160.
A lever may be defined based on a location of the input force
(effort), the fulcrum, and the resistance (the load) with a class 1
lever having the fulcrum placed between the effort and load, a
class 2 having the load between the effort and the fulcrum and a
class 3 lever having the effort between the load and the fulcrum.
In the example embodiment shown in FIG. 20, the sleeping platform
may form a class 1 lever with the fulcrum defined by the roller 137
being between the input force p and the resistance or load provided
a portion of the weight w1 of the outer front panel 130A.
In a fourth operation to unfold the chest 100, the user may
continue to unfold the inner front panel 130B by, for example,
pulling further on the strap 400 to provide an input force p to the
lever formed by the sleeping platform.
Referring to FIG. 20 in conjunction with FIGS. 21 to 24, to bring
the outer front panel 130A and the inner front panel 130B into a
single horizontal plane to form a portion of the sleeping platform
that supports the mattress 500, an external force p that overcomes
the weight w1 of the outer front panel 130A may be applied by the
user resulting in upward movement m of the outer front panel
130A.
Due to the configuration of the lever, the external force p applied
by the user is aided by the force of the weight w2 of the lower
support since both forces are on a same side of the fulcrum defined
by the roller 137. As illustrated in FIG. 24, in this position, the
distance "a" between the center of the weight w2 of the inner front
panel 130B and the fulcrum (e.g., the roller 137) is substantially
larger than the distance "b" between the center of the weight w1 of
the outer front panel 130A and the fulcrum. As such, the inner
front panel 130B may provide a mechanical advantage, to reduce (or,
alternatively, minimize) the external force p provided by the user
to bring the outer front panel 130A and the inner front panel 130B
into the single horizontal plane. The downwards motion of the inner
front panel 130B and the lifting of the outer front panel 130A in
the fourth operation tends to move the center of the weight w2 of
the inner front panel 130B further from the fulcrum such that the
magnitude of the input force p provided by the user decreases as
the user continues to unfold the inner front panel 130B until a
transition point is reached at a mid-angle, where the input force p
will diminish to zero, and the lever will be a perfect balance
between the center of the weight w2 of the inner front panel 130B
and the center of the weight w1 of the outer front panel 130A
acting through the first hinge 121.
Beyond this point, as illustrated in FIGS. 21 and 22, the direction
of the input force p applied by the user changes to support a
portion of the weight w2 of the inner front panel 130B, until the
front legs 135 are lowered to the ground to support the sleeping
platform.
Referring to FIGS. 25 to 28, in the final static position, the
outer front panel 130A and the inner front panel 130B are
horizontal providing a portion of the sleeping platform for the
mattress 500 with the weight w1 of the outer front panel 130A
supported between the second hinge 131 and the first hinge 121, and
the inner front panel 130B stably supported by the front legs 135
and the rear legs 136 with the roller 137 having moved rearwards
coming to a final position almost under the first hinge 121.
Considering the inner front panel 130B as a lever with the fulcrum
at roller 137, with the weight w2 of the inner front panel 130B on
one side of the fulcrum and the weight w1 of the outer front panel
130A acting on the other side of the fulcrum, a substantial
difference may exist between a distance "c" from w2 to the fulcrum
as compared to a distance "d" of w1 to the fulcrum. This difference
in distances may provide mechanical advantage to aid resisting the
sleeping platform from collapsing back to, for example, the
position of FIG. 24 due to an increase in weight from, for example,
the mattress 500 and the sleeping user.
FIGS. 29 to 31 illustrate a kit including a chest configured to
store a foldable bed and a mattress according to example
embodiments.
Referring to FIGS. 29 to 31, the chest 100 may be included in a kit
along with the mattress 500 or may be separately provided with the
mattress 500 to form the kit.
In a fifth operation to unfold the chest 100, the mattress 500 may
be removed from the enclosure inside the cabinet 100, and the
folding slat deck 200 may be unfolded so that the holding slat deck
200 is substantially in the same horizontal position as the outer
front panel 130A and the inner front panel 130B, thus, forming the
sleeping platform for the mattress 500. Thereafter, the mattress
500 may be unfolded and placed on the sleeping platform. For
example, as shown in FIG. 31, in an effort to avoid placing a
crease of the mattress in a middle of a user's body, the mattress
may include two separate folds located on an upper third and a
lower third of the mattress 500 such that the mattress 500 is
unfolded by unfolding the lower third and the upper third of the
mattress 500.
FIGS. 32 to 34 illustrate a method of folding a chest from an open
or unfolded position to a closed or folded position according to
example embodiments.
Referring to FIGS. 32 to 34, to fold the chest 100, a user may
perform a reversal of the process discussed above with regards to
unfolding the chest 100. For example, in a first operation
associated with folding the chest 100, the user may provide an
upward force p lifting the full weight w2 of the inner front panel
130B.
Thereafter, the upwards motion of the inner front panel 130B and
the lowering of the outer front panel 130A, causes the rollers 137
to move away from the chest 100 (e.g., towards the user) such that
the center of the weight w2 moves closer to the fulcrum (e.g., the
rollers 137), and, thus, the rollers 137 support more of the weight
w2 of the inner front panel 130B. The magnitude of the input force
p provided by the user decreases as the user continues to fold the
inner front panel 130B until a transition point is reached at a
mid-angle, where the input force p will diminish to zero, and the
lever will be a perfect balance between the center of the weight w2
of the inner front panel 130B and the center of the weight w1 of
the outer front panel 130A acting through the first hinge 121.
Beyond this transition point the user will not need to provide any
further forward force, only a light reverse force to keep the
motion of the inner front panel 130B under control until the lower
support is back at rest similar to that of FIGS. 13 and 14. As the
outer front panel 130A moves back to a vertical position as the
chest 100 is closed, the pivoting guards 160 may remain extended
due to the offset of their pivot point. Thus, the user may manually
apply a force to the pivoting guards 160 to urge the pivoting
guards 160 to retract back into the enclosure.
FIGS. 35 to 42 illustrate a chest configured to store a foldable
bed according to some other example embodiments.
Referring to FIGS. 35 to 42, rather than the rear legs 136 angled
towards the rear of the inner front panel 130B to allow sufficient
clearance between the rear legs 136 and the top panel 120 when the
inner front panel 130B is folded into the chest 100, in some
example embodiments, the chest 100 may further include the rear
folding leg assembly 300. The rear folding leg assembly 300 may
include the rear legs 136 having the rollers 137 extending from a
bottom thereof.
The rear folding leg assembly 300 may be connected to the first
portion 120A-1 of the first sub-top panel 120A. For example, a
first one of the first portion 120A-1 and the rear folding leg
assembly 300 may include a slot therein and the second one of the
first portion 120A-1 and the rear folding leg assembly 300 may
include a protrusion thereon, where the rear folding leg assembly
300 is configured to pivot from a closed position to an open
position by rotating of the slot about the protrusion, and
subsequently secured into place by applying a force to slide the
folding leg assembly towards the upper front panel 120A.
The rear folding leg assembly 300 may allow the rear legs 136 to be
folded so that there is sufficient clearance between the rear legs
136 and the top panel 120 when the inner front panel 130B is folded
into the chest 100 while placing the rear leg 136 directly under
the first hinge 121 to increase a stability of the sleeping
platform by removing a lever action urging the inner front panel
130B to fold.
The description of the disclosure is merely example in nature and,
thus, variations that do not depart from the gist of the disclosure
are intended to be within the scope of the disclosure. Such
variations are not to be regarded as a departure from the spirit
and scope of the disclosure.
